The 5ghz Quantenna radio on the RT-AC87U is notorious for being absolute pants (very unstable), largely due to poor firmware by Quantenna. If 5ghz wifi is a must, you're better off binning this and getting a router with Broadcom or Qualcomm radio chipsets which will be far better. E.g. Asus RT-AC88U, Netgear R7800, linksys EA8500 etc. The 2.4ghz radio on the AC87U is by Broadcom which is stable.
